Abstract
A spring-actuable friction clutch, having a disk carrier and a cup spring which is connected to the latter via screwed connections. Threaded sleeves are arranged fixedly on the disk carrier. The cup spring has openings which are penetrated by the threaded sleeves. A holding ring is arranged on that side of the cup spring which faces away from the disk carrier. Bolts penetrate passages of the holding ring and are screwed into the threaded sleeves. In a friction clutch of this type, particularly simple mounting and fastening of the cup spring on the disk carrier is ensured.
